removing the steering spindle shaft from the gear on the shaft.
I have tried driving it down with a big hammer, but will not move,The shaft won"t drive through the quill. Any ideas, what works?
Thank you for any advice

The shaft won't go through the quill until the power steering vanes are removed from it.
The gear needs to be loosened first. I remove the original bolt and install a long bolt that sticks up out of the top so you can get a good hit on it. Better if done while still in the tractor so gravity helps you. You may have to lift up on the gear and put some kinda blocks or wedges under it so you know it is not bottomed out down inside. Also measure the free play so you can adjust it right when going back together.

Look though the pictures I have posted to see how I did it. Look for this paragraph:

Worked some more this evening, still cold though. Had a good idea after being unsuccessful getting the steering gear to come off. I made a wood box frame with a 6.5 inch square inside measurement. The spindle quill sits down inside and is supported well above a scrap of 2x12. This allowed the assembly to be firmly supported while I pounded on the pedestal from above to drive it down through the steering gear. Only a few sharp wraps were needed to loosen the the gear, then using the hoist the housing was lifted from the pedestal. Now to look closely at the parts for signs of wear and locate o-rings and seals.

Mike, I had viewed your photos previously, it was very helpful, I made the 2x12 block to help with the removal, but just wont break loose.
Didn't want to hit too hard with the 2x2 block and 12lb sledge. I have raised the unit about 1 inch from the 2x12s with a chain

Looks very similar to the overhaul of my JD 50 which was leaking. Did not have any trouble with the shaft and pedestal. Most of the leakage on mine was due to the cork seal. When I replaced the vanes I also put in new pins as they get a lot of wear going back and forth and can get out of round. I show friends of the mine pictures of the steering pedestal and they can't believe how strong John Deere engineered the two cylinder steering setup. Guess that is why they can last for 50-70 years without rebuilding. Went to JD dealership and order a case of John Deere 2 cylinder power steering fluid and was good to go.
